Geothermal Loop

What are geothermal loops ?

In a geothermal heating system, we call “geothermal loops” the pipes that are buried in the ground. They are called geothermal loops because they start from one point, create a circuit under the ground and come back to that same point. The geothermal loops are filled with a carrier liquid (a mix of water and antifreeze) that absorbs the heat of the earth as it runs through the geothermal loops and brings it back to the heat pump to create electricity. The geothermal loops are also often called simply geothermal “wells”.
